Map Can Be Displayed Anywhere

Filed under: Uncategorized — Fei Du @ 7:08 pm

The advantage of mobile mapping applications is their portability and convenience. People can get geographic information almost anywhere at any time. However, the small screen size may also cause some map readability problems for the users.

In a new concept device called “Maptor” , street map is projected out as a huge screen display, either on the wall, floor or any flat surface for better visibility. With GPS component, your current location will be highlighted.  This is really innovative for me because it integrates both the portability of mobile devices and the readability of large screen.

The problem of concern is whether it can do a good job in the daylight. At least, it is a very cool at night or in a group of people touring a city.

Besides project image to a tangible surface, there are already some products in the market which can project image to the air, e.g. IO2 Heliodisplay. A very important feature is it provides us free space interactivity.

Future display devices will become even more diverse, therefore map can be displayed anywhere and become ubiquitous.

  1. I know they’ve been building a very interesting approach to mobile computing at MIT for some time that combines (1) a micro-sized projector warn around the neck + (2) a camera for image/scene/barcode etc. recognition (like Google Googles) + (3) gesture based interface.

    The big drawback: Privacy. Even the inventors admit they wouldn’t want to check their email or do their online banking projected onto a wall.

    • I think the system you mentioned is called “The Six Sense” that is developed by MIT’s Media Lab. It is really cool.

      Speaking of privacy, something can be displayed publicly (like a map) while something cannot (like bank account information). Different display devices can be integrated and be complementary to each other. Users can decide how to use them.
